ㄴ다거나 하다

…, or something along those lines

This offers an example without claiming it is the only one — the Korean equivalent of tacking 'or whatever' onto a case you just named: 앙코르를 원하신다거나 하는데 'if they ask for an encore or something', 위로의 말을 대신한다거나 하기도 하는 것 같습니다 'it stands in for words of comfort, or something like that'. It softens a statement so it doesn't sound like an exhaustive list. Every line here is mid-sentence — this belongs in explaining, not in short replies.
